I have imported a shapefile into CartoDB (it is the only one I can get my hands on, since it's a small geographic region, non-US) - it includes shapes of all the municipalities in a federal state. It turns out though that the shapefile creates two seperate maps when imported into CartoDB, because of some bureaucratic distinction the state makes in regard to its municipalities.
I would like to have all the shapes of the municipalities in one map and one layer, so I can join sets of data (that normally just include all the municipalities in alphabetic order) easily and also use the info window function for all shapes.
I tried merge tables, but that function seems to be for different types of merges. I tried opening one of the maps and typing out the missing municipalities in new rows in the data window (to trick the column merge) but it appears that the column that has the geospatial info in it is not supported by the merge function.
